KNOWLEDGE OF LED LIGHT BEAM ANGLE AND HOW TO CHOOSE IT
published date: 2017/10/22

The light source or light emitted by the lamp is not covered in the whole space, and they all have a certain point of view, that is, the light source or the lamp can reach the range is limited, and the beam angle is the angle of the beam of the light source or the lamp, which is the angle formed by the intensity of the beam.

CIE(international lighting board): on the plane of the beam axis, the central point of the lamp is the axis, the area of the peak center of the intensity of 50%. Generally speaking, the beam angle of narrow beam is less than 20degrees, and the beam angle of medium beam is 20 degrees to 40 degrees, and the beam angle of medium beam is 20degree to 40 degrees, and the beam angle of broad beam is more than 40 degrees.

Effect comparison of different beam angles

 

                                                                               

So, how to choose the light, we have some little suggestion that if the light is to be directed on a specific object or person, not an area, there need to choose narrow beam angle;

when you are lighting up a large room etc, there need to choose wide beam angle;  Like led downlight with wider beam angle, 60degree very very popular in market.

So, we suggest you choose narrow beam angle led light if in museum or cloth room etc, choose wide beam angle light if in big housing or market etc.
